Existing pharmaceutical studies show that Magnolia biondii is effective in treating rhinitis and in reducing cholesterol, given its endogenous, volatile ingredients. The study herein seeks to assess the cosmeceutical activities and anti-inflammatory activities of Magnolia biondii extracts for possible application as cosmetic ingredients. The cosmeceutical and anti-inflammatory activities were investigated using hydroxyl radical scavenging, superoxide dismutase (SOD)-like activity, xanthine oxidase (XO) inhibition, cell viability, nitric oxide (NO) inhibition, and inducible nitric oxide synthase (iNOS) expression by Western blotting. Magnolia biondii extracts were identified to have antioxidant activities in hydroxyl free radical scavenging, SOD-like activity, and XO inhibition. In testing the anti-inflammatory activities of the extracts, NO production was inhibited in a dose-dependent manner. Additionally, in a dose-dependent manner, the Magnolia biondii extracts were able to suppress iNOS expression in LPS-stimulated RAW 264.7 macrophage cells. From these results, Magnolia biondii showed adequate potential for application in cosmetic production and related industries as well as a functional material.

This study attempted to investigate the effects of Paeonia Lactiflora Pallas (P. lactiflora) on the inhibition of oxygen free radical, anti-inflammation and MMP-1 inhibitory activity and examine its possibility as a functional cosmetic material. For test methods, the inhibition of oxygen free radical after measuring reactive oxygen species (ROS) in the cell, cytotoxicity assessment and anti-inflammation were measured, and MMP-1 inhibitory effects in the HDF cell were measured. According to the test, the inhibition of ROS was confirmed in RAW 264.7 and HDF cells. In terms of cytotoxicity assessment, 90% or higher cell viability was detected at $5/10{\mu}g/mL$ Paeonia Lactiflora Pallas extract while it was 80% or higher at other concentration levels in both RAW 264.7 and HDF cells. In addition, NO production was inhibited in the RAW 264.7 cell while MMP-1 was significantly inhibited in the HDF cell. The above results reveal a possibility of Paeonia Lactiflora Pallas extract as a functional cosmetic material after confirming the inhibition of ROS synthesis in the cell, antioxidant and anti-inflammatory effects by inhibiting NO synthesis, low toxicity on skin cells and anti-aging effect through MMP-1 inhibition.

Acer tegmentosum Maxim (ATM) is known as traditional medicine for treatment of hepatic disorders such as hepatitis, related-inflammatory disease, and hepatic cancer. In this study, we evaluated the antioxidant and anti-inflammatory effects of ATM extracted with $80^{\circ}C$ water or 95% ethanol. Antioxidant activities of ATM extracts were measured based on DPPH and ABTS radical scavenging activities, total polyphenolic compound contents, and ferric reducing antioxidant power. The anti-inflammatory effects of ATM extract were assayed on release of nitric oxide, tumor necrosis factor $(TNF)-{\alpha}$, and interferon $(IFN)-{\gamma}$ from lipopolysaccharide (LPS)-induced macrophages. In these experiments, 95% ethanol extract of ATM showed stronger antioxidant and anti-inflammatory effects than water extract. Therefore, we determined the effects of ATM ethanol extract on an animal model of sepsis. Seven days oral gavage of ATM ethanol extract followed by LPS stimulation reduced the protein levels of $TNF-{\alpha}$ and $IFN-{\gamma}$ in serum as well as mRNA levels of $TNF-{\alpha}$ and interleukin-6 in intestinal epithelial cells. In addition, ATM ethanol extract reduced DNA damage in mouse lymphocytes. These results indicate that ATM extract has strong antioxidant and anti-inflammatory in vitro and in vivo effects and may be developed as a potential food material for prevention of inflammatory diseases.

Pholiota nameko is an edible mushroom belonged to Family Strophariaceae of Agaricales, Basidiomycota. The purpose of this study was to investigate the antioxidant and anti-inflammatory activities for the methanol and hot water extracts prepared from fruiting bodies of Pholiota nameko. Besides measuring for 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, a reducing power and a chelating activity on ferrous ions were also measured to evaluate the antioxidant activity for those extracts. To measure the anti-inflammatory activities for the extracts, nitric oxide(NO) production from lipopolysaccharide treated RAW 264.7 macrophage cells and carrageenan-induced acute hind paw edema of rats were investigated. The results showed that those extracts has a excellent chelating activity on the ferrous ions compared with positive controls. And it also turned out that extracts had a good DPPH activity and a reducing power. The NO production in LPS-treated RAW 264.7 macrophage cells were decreasing as we increased concentration of those mushroom extracts. Significant reduction of paw edema were also observed at 2~6 h after we treated methanol and hot-water extracts at the 50 mg/kg concentration to the rats which are induced acute hind paw edema by carrageenan treatment. The experimental results suggested that methanol and hot-water extracts of Pholiota nameko fruiting bodies might be used for potential source of antioxidant and anti-inflammatory agents.

The antioxidant and anti-inflammatory effects of active ingredients in cosmetics are very important. The effects are closely related to the prevention of skin aging. Among medicinal plants, Bletilla striata Reichenbach fil. has well-known pharmacological activity. Extracted samples were prepared using sequential fractionation of ethyl acetate, butanol, and water. The antioxidant effect of the fractions was confirmed by DPPH and ABTS+ radical scavenging. Among the various fractions of B. striata Reichenbach fil., ethyl acetate was associated with a reduction in nitric oxide production, which was induced by LPS (lipopolysaccharide) treatment in a dose-dependent manner. In addition, the production of iNOS (inducible nitric oxide synthase) and COX-2 (cyclooxygenase-2), which are upstream regulators of nitric oxide production, was also inhibited. Thus, the ethyl acetate fraction of B. striata Reichenbach fil. appears to be a potential active ingredient for use in cosmetics.

In this study, the ginsenoside contents and anti-inflammatory effects of white ginseng (WG) and puffed red ginseng (PRG) were compared. The contents of Rb1, Rg5 and Rk1 were significantly higher in PRG than in WG, whereas the contents of Rg1 and Rb2 were decreased in PRG. The levels of NO production and iNOS expression were suppressed in LPS-stimulated cells by treatment with WG and PRG. Further, the production of cytokines (TNF-$\alpha$ and INF-$\gamma$) and inflammatory proteins (NF-${\kappa}B$ and COX-2) was decreased in cells upon treatment with any of the ginsenosides. The high NO inhibitory activity and cytokine production of PRG is caused by differences in the composition of ginsenosides produced.

This study investigated the anti-inflammatory activity of barley leaf extract in lipopolysaccharide (LPS)-stimulated RAW264.7 cells and hairless mice. Pre-treatment with barley leaf extract significantly inhibited the protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-II (COX-II) in a dose-dependent manner in LPS-stimulated RAW264.7 cells. Barley leaf extract also significantly inhibited the secretion of inflammatory cytokines, such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), and interleukin-6 (IL-6). Moreover, phosphorylation of mitogen-activated protein kinases (MAPKs) and nuclear translocation of nuclear factor-kappa B (NF-${\kappa}B$) were strongly suppressed by barley leaf extract in LPS-stimulated cells. In hairless mice, barley extract significantly decreased the pathological phenotypes of contact dermatitis, such as erythema, edema, and scabs. These results indicate that barley leaf extract has an anti-inflammatory effect and therefore a possible role in the treatment of inflammatory diseases or in functional cosmetics.
